Change the camera’s video recording settings on iPhone
By default, iPhone video records at 30 frames per second (fps). Depending on your model, you can choose other frame rates and video resolution settings. Faster frame rates and higher resolutions result in larger video files.
You can also use quick toggles to easily change video resolution and frame rates right on the camera screen.
Use quick toggles to change video resolution and frame rate
In Video mode, use quick toggles at the top of the screen to change the video resolution and frame rates available on your iPhone.
On iPhone XS, iPhone XR, and later, tap the quick toggles in the top-right corner to switch between HD or 4K recording and 24, 30, or 60 fps in Video mode.
To display quick toggles on iPhone X and earlier, go to Settings > Camera > Record Video, then turn on Video Format Control.
Adjust Auto FPS settings
On iPhone XS, iPhone XR, and later, iPhone can improve the video quality in low-light situations by automatically reducing the frame rate to 24 fps.
Go to Settings > Camera > Record Video, then do one of the following:
On iPhone 12 models, tap Auto FPS, then apply Auto FPS to only 30-fps video or to both 30- and 60-fps video.
On iPhone XS, iPhone XR, iPhone SE (2nd generation), and iPhone 11 models, turn on Auto Low Light FPS.
Turn stereo recording on or off
On iPhone XS, iPhone XR, and later, iPhone uses multiple microphones to achieve stereo sound. To turn off stereo recording, go to Settings > Camera, then turn off Record Stereo Sound.
Turn HDR video off and on
On iPhone 12 models, iPhone records video in HDR and shares HDR videos with devices using iOS 13.4, iPadOS 13.4, macOS 10.15.4, or later; other devices receive an SDR version of the same video. To turn off HDR recording, go to Settings > Camera > Record Video, then turn off HDR Video.
